30116pb03, Panel 14x14x2.667 with Millennium Falcon Pattern - Daniel Goerner - 2012-03-14

Can someone please check these files if I have overseen anything? Edger2 says the subfile is okay, but who knows?
Maybe some advice what I could do better (sorting the colors or whatever). And any help with the Header would be appreciated (Filename, Tags maybe?)...

When did I make that "without faces" subpart? 8 years ago? And you beat me to this pattern. lol. Good job man!

Very good job indeed!

Well... not quite, I see 4 red lines that at closer look are caused by needle shaped gaps.

And LDDP does report a few errors (see below).

Most can be split into appropriate triangles to solve the problem .
As for the header, I suggest the use of Datheader... that will not only correct headers issues (missing space in front of 2.667, ö of your name converted to UTF8) but also most of previous problems (only 2 very thin triangles remain).

How did you do projection on surface? Using Slicerpro? then maybe playing a bit with "precision" and/or unification thresholds would have eliminated some of the issues from the start?

That must have happened after I used Slicerpro. Before using it everything was alright.

I now used Datheader on the original Patterm, before projecting it. 6 Errors remain:

I don't know what this means (like the stuff you posted, remember, I never did this before). I think there are vertexes placed on top of each other. But I don't know how to find, correct or eliminate them.

Yes, i used Slicerpro. Very cool tool. I made the part with stickers (using Sticker Generator) before and it was torture to place them right. I'll try to play around with the settings tomorrow.

Yes, there are some less-than-perfect things in Slicerpro, and sometimes it easts a triangle or two... I have a slightly better version than the one on my website, but not yet published since some problems remain.

Quote:I now used Datheader on the original Patterm, before projecting it. 6 Errors remain:
Here too I may be the culprit. LPC uses a slightly modified version of Rectifier to assemble triangle pairs into to quads. The first 5 errors with very flat angle quads should not happen (except if the triangles in your pattern had very flat angle). The last problem comes from a very sharp angle triangle that you created in your pattern (needle shaped triangle). This should be avoided, there are generally ways of organizing triangles differently to avoid this.

Coud you share the .lpc file of your pattern? (rename it to .txt so that it's accepted on the forum, or email it directly to me...)


Re: 30116pb03, Panel 14x14x2.667 with Millennium Falcon Pattern - Daniel Goerner - 2012-03-15

You've got mail.

Oh, and Chris, if you're reading this, could you give me a partno. for this?


Re: 30116pb03, Panel 14x14x2.667 with Millennium Falcon Pattern - Daniel Goerner - 2012-03-15

Short question: Can I split a quad into two triangles again, and if so, how?


Re: 30116pb03, Panel 14x14x2.667 with Millennium Falcon Pattern - Philippe Hurbain - 2012-03-15

Yes, with a text editor... For example:
Code:
p1                       p2                    p3 (too flat angle)   p4
4 6     23.86372 0 -160.7092     48.374 0 -174.727     47.547 0 -171.369     46.777 0 -168.254
gives
Code:
p1                       p2                    p3
3 6     23.86372 0 -160.7092     48.374 0 -174.727     47.547 0 -171.369
        p3                       p4                    p1
3 6     47.547 0 -171.369        46.777 0 -168.254     23.86372 0 -160.7092
or
Code:
p2                       p3 (too flat angle)   p4
3 6     48.374 0 -174.727        47.547 0 -171.369     46.777 0 -168.254
        p4                       p1                    p2
3 6     46.777 0 -168.254        23.86372 0 -160.7092  48.374 0 -174.727

Of these two possibilities, the 1st one is the right since it splits in half the very flat angle.


Re: 30116pb03, Panel 14x14x2.667 with Millennium Falcon Pattern - Travis Cobbs - 2012-03-15

Doesn't LDDP have a command to split a quad into two triangles?


Re: 30116pb03, Panel 14x14x2.667 with Millennium Falcon Pattern - Philippe Hurbain - 2012-03-15

Travis Cobbs Wrote:Doesn't LDDP have a command to split a quad into two triangles?
No, it's the other way around (merge 2 triangles into 1 quad). Splitting poses a UI problem (especially at text level) since there is a choice to do between the two possible splits...
